Implementation of the Dynamic TOPMODEL Hydrological Model

A native R implementation and enhancement of the Dynamic TOPMODEL semi-distributed hydrological model. Includes some preprocessing, utility and routines for displaying outputs.


Version 1.2.1


  • Return flow is calculated by determining by any excess over limiting transmissivity of net upslope input.


  • A logical error has been fixed in the calculation of maximum subsurface lateral transmissivity. This meant that too much surface runoff was being generated at low values of ln_t0.
